Question

Organic Chemistry Lab: If the approximate melting point of a sample is known, at what point compared to the anticipated melting point do you considerably slow down the rate of the heating? What is the rate you should heat the sample at after this point?

What I think: Generally, you need to give enough time for heat to be transferred equally from heating block to sample to the thermometer. If you go too fast, temperature at sample is very different than temperature at thermometer, and sample appears to have a wide range. However, I am not sure exactly WHAT POINT compared to the anticipated melting point too slow down the heating, and what rate you keep this at.
